1 Samuel 13:9

It is, to say the least, doubtful whether Saul offered the sacrifice with his own hands, or whether he caused it to be offered. At any rate, his offence was not in his offering sacrifice, but in his unwillingness to obey the directions of God and of God'srepresentative, the prophet. It must be admitted that Saul's position was a difficult one; but this single act was really an index to a weakness in his character: see, however, on 1 Samuel 14:24.
